Summary

The Calderdale and Kirklees Energy Savers (CAKES) scheme, launched in September 2000, was co-ordinated by Kirklees Energy Services (KES) which is a SAVE agency, in conjunction with Calderdale Metropolitan Borough Council (MBC) and Kirklees Metropolitan Council (MC). By providing advice, registered installers, fixed discount prices, preferential credit facilities and cash backs (funded by HECAction, TXU, Scottish Power and the European Commission) this scheme offered householders (ineligible for other government funded Home Energy Efficiency schemes) in Calderdale and Kirklees financially viable, easily accessible and energy efficient heating and insulation measures. Despite initial setbacks with unprofessional installers, 'CAKES' enabled the installation of many energy efficient measures in these districts, thereby reducing escaping energy, utility bills and most importantly CO₂ emissions. This scheme is highly replicable, especially where councils/ municipalities are willing to offer a lump sum of money for cash backs and if the scheme is reproduced in a small region, then expanded.

Results

Table: Number of household involved in the scheme.

Note: 2003 figures only up until 14/09/03.

The table above shows that a total of 1455 households in all districts were involved in 'CAKES'. The majority of these households were in Kirklees and the greater part of work took place in 2001. The next table displays the measures installed.

Table: Measures Installed

Note: 2003 figures only up until 14/09/03.

The table above shows that, to date, a total of 2080 energy efficient measures have been installed. Cavity wall insulation has been most often installed, followed closely by condensing boilers, while floor insulation has been installed least of all. The larger amounts of installations in 2001 and 2002 are most probably caused by the fact that the scheme was run for the whole of these years and because the majority of measures were installed in winter.

The next table displays the savings that were achieved through the installation of energy efficient measures.

# This figure (€ 0.046) was calculated from a representative sample of households who had energy efficient measures installed. Wherein, 5 % used electricity, 95 % used gas, and gas prices were at € 0.043 and electricity at € 0.107.

The table above shows a lifetime CO₂ saving of 34, 304.24 tonnes when compared with the life cycle of the measures installed. Overall the above results suggest that 'CAKES' has achieved high installation levels of energy efficient measures in a number of households in Kirklees and Calderdale. In turn this has assisted to reduce CO₂ emissions. Thereby, 'CAKES' is assisting Britain to obtain their CO₂ target for Kyoto and HECA.

Alongside the above savings, 'CAKES' has helped to develop an approved discount local installer network. This will not only benefit subsequent schemes within KES but may result in prices of energy efficient measures being driven down in the general community. Most importantly, 'CAKES' has increased thermal comfort in households, alongside increasing individuals' disposable income (savings in utility bills). Moreover, 'CAKES' has helped to raise energy efficiency awareness in West Yorkshire and had increased local employment.
